I'd be very grateful for any information with regard to John and his family during this timescale.
I have found John's wife Jessie W Edgar (maiden name unknown) travelling from Southampton to South Africa on the 'Edinburgh Castle', 23 December 1921. She is travelling with their 4 children aged 1-8 and his spinster sister, Mary Cameron Edgar. (EDIT: I don't have a marriage or birth of any of the children. I only have the names of 2 girls Rena b 1913 and Mary b 1917 from the 1939 Register)
In the UK 1939 Register the family are living at 109 Claremont Road, Forrest Gate, London with sister Mary Cameron Edgar (who dies at that address in 1956)
I know that John dies in 1951 at Poplar, London.
Ancestry has an entry in the Transvaal Province, South Africa, Estates Death Notice Index, 1855-1976, but doesn't provide an image. Can anyone advise how I would gain access to this and would it just be a date entry or would there be some narrative which would be helpful for my records?
A Google search has brought up the S2A3 Biographical Database of Southern African Science, which mentions John:
Qualified (MRCVS) in Edinburgh in December 1895 and came to South Africa as an officer in the Army Veterinary Division of the British forces during the Anglo-Boer War. After the cessation of hostilities he joined the Veterinary Division of the Transvaal Department of Agriculture in November 1902, where he served until his retirement in May 1928. He obtained a Diploma in State Veterinary Medicine in 1921. For some time he was stationed at Pietersburg and was mainly responsible for the eradication of East Coast Fever in the Northern Transvaal. He published a short review of animal diseases in 1911.
Any information would be helpful and many thanks in advance, Kit
